TOBOGGAN.

. Application filed February 15, 1886.

CYTFICATION forming part of Letters Patent No. 339,690, dated April 13, 1886.

Serial No. 191,951. (No model) To all whom, it may concern:

Be it known that we, \VILIIAM H. 'PROCTOR and S. l-l'annrson MILLER, citizens of the United States, residing at Ogdensburg, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Toboggans, of which the fol lowing is a specification, reference being had therein to the accompanying drawings.

lhe object of our inventionis to provide toboggaus of simple construction, which will combine with suitable lightness and convenience the greatest possible strength and durability, and which will present on their under sides frictional surfaces of lesser extent than the toboggans heretofore generally in use.

In the accompanying drawings, Figure 1 is a plan view of a toboggan embodying ourinvention. Fig. 2 is a side view, partly in section, of the same. Fig. 3 is a cross-section on the line 3 3, Fig. 1; and Fig. 4 is a cross-section showing a slightly modified form of our invention.

The body of our toboggan is composed of strips A,seeuret1 together by cross-bars B, the latter being preferably attached to the strips by screws I), inserted from the tops or upper sides of the cross-bars and entering but not passing entirely through the strips, thus leav- 0 ing a smooth surface at the bottom of the toboggan. If the screws be inserted from the bottoms of the toboggans, the countersinks for the heads of the former will occasion more or less roughness," while if the screws be inserted 5 from the tops of the cross-bars and passed entirel y through the strips they will, even though filed off smoothly in the first instance, eventually project more or less below the bottoms of the strips, as the latter, which are of wood, 0 and thus softer than the metal screws, wear away in use. For this reason we prefer to insert the screws from the tops of the cross-bars and to have the screws sufficiently short, so that they will terminate above the lower sur- 5 faces of the strips A.

To lessen the friction of the under surface of our toboggan 011 the snow or ice, we prefer to make the strips A of varying or different thickness, so that the weight of the tobog- 5o gen and its lead will be carried by a portion only of these strips. In Figs. 1 and 3 we have shown an alternate arrangement of these thick and thin strips, and this arrangement we consider the best; but these thick and thin strips may be diiferently placed, for example as illustrated by Fig. 4, in which two th1n strips are shown between each of the thicker ones..

0 denotes the side-rails of the toboggan, these strips being preferably secured in place by means of screws 0, inserted from the tops or upper sides of the rails and of proper length not to pass entirely through the strips A.

0 admit of the use of a greater number of screws 0 than would-otherwise be practicable and to give additional strength to the toboggan, we prefer to use filling or bracing blocks D between the side rails and the strips A, these blocks being of proper length to fit between the cross-bars B. These blocks will, however, be omitted from between some of the cross-bars, to enable the side rails to be conveniently grasped by the rider, the number of the open spaces 0' varying according to the length of the toboggan. lhe filhngblocks D are preferably secured to the strips A by screws a, passing from the tops of said blocks downward into but-not passing entlrely through the strips A. Thestrips A are curved over at their forward ends to give the usual form to the toboggan, and to these ends of the strips we secure, by nails, screws, pins, or otherwise, a block, E, having a groove in which the ends of the strips are entered, the said block thus serving to give a finish to the 8 5 ends of the strips and to hold the latter strongly in place.

The curved front end of the toboggan 1s braced or secured to one of the cross-bars or to the side rails by ordinary rawhide or gut 9O fastenings, f, preferably passing through the grooved block E.

Having thus described our invention, we claim and desire to secure by Letters Patent 1. A toboggan the body of which is composed of flat strips of varying thickness, the bottoms of the thinner strips being above the bottoms of the thicker strips, so that the weight is entirely supported by the latter, combined with cross-bars secured to said strips and servco ing to hold them firmly together, substantially as set forth.

2. A toboggan the body of which is com; posed of alternate fiat strips of varying thickness, the bottoms of the thinner strips being above the bottoms of the thicker strips, so that the weight is entirely supported by the latter, combined with cross-bars secured to said strips and serving to hold them firmly together, substantially as set forth.

3. In a toboggan, the combination, with the flat strips of varying thickness composing the body of the same, and the cross-bars by which said strips are secured together, of the fasten.- ing-screws passing from the tops or upper sides of the cross-bars downward through said bars and into the strips and terminating above the lower surfaces of the latter, substantially as set forth.

of the strips and into which the said ends are entered, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
